Реши примеры: 12 - 2 + 4, 12 - 2 + 5, 12 - 2 + 7, 13 - 3 - 2, 14 - 4 - 5, 16 - 6 - 3, 10 + 5 - 1, 17 - 7 + 6, 10 - 8 + 8.

Решение:

• \( 12 - 2 + 4 = 10 + 4 = 14 \)
• \( 12 - 2 + 5 = 10 + 5 = 15 \)
• \( 12 - 2 + 7 = 10 + 7 = 17 \)
• \( 13 - 3 - 2 = 10 - 2 = 8 \)
• \( 14 - 4 - 5 = 10 - 5 = 5 \)
• \( 16 - 6 - 3 = 10 - 3 = 7 \)
• \( 10 + 5 - 1 = 15 - 1 = 14 \)
• \( 17 - 7 + 6 = 10 + 6 = 16 \)
• \( 10 - 8 + 8 = 2 + 8 = 10 \)

Ответ: 14, 15, 17, 8, 5, 7, 14, 16, 10.
